Application filed December To all whom it may 0015mm:

ing of the operation of the various parts of the maul no end glassseeding or charging mechanism inchidiiig the shearing or cut-oil?mechanism, order chat they may cooper-etc satisfactorily.

Therefore, one feature of the invenbion consists in the combinationwiththe spout of a glass rsrik and a glass making machine so locatedwith reference to the spout, substantially under it, that the glass maypass directly from the sy 'iufo to the mold in the. nmchinc, snd meensIor cutting oil the glass and controlling its delivery from the spout,to the mold so as to make ii; operate satisfactorily. I

Another feai'ure of the invenizion consists in the sheer mechanism whichnot only cuts oft" the gather of glass, but temporarily receives andsupports ighe remainder of the glass which has flowed from the spout ofthe tank so as to retain it and form it initially for constituting apart. of the next gather of glass. In such mechanism there is a. knifei'xoo 'iemt-ing with the sheer bar which has an opening through it forthe to descend, and when the knife shears the glass, it closes thebottom. of said open ing and thereby forms a cup, endinesns to holdthe'knife temporarily in that position until the desired function hasbeen accomplished before the knife begins in return to its inoperativeposition. To return the knife, it is first. moved downward away from theglass retained: in the cup of the shear bar. Also-during the operationof temporarily holding the glass, the cutting mechanism is moved upcloser to the dis charge opening in the spout in order to receive theremaining glass and cause it to GLASS-FEEDING MECHANISIM.

fill the cup, and as soon as this is accomplished and the knife beginsto lower away from the shear bar through the sheer her opening bygravity to form the next gather, the sheer bar is gradually moveddownward, not only to normal-position, but lower.

Another feature of the invention consisds in combining with the aboveshearing mechanism, a needle or plug operating verticelly in the spentfor opening and sub stirotielly closing the discharge outlet, therefrom, in tii'ne'd relation with said shear mechanism. To that end theplug or needle is operated by the same means as opera-tee the shearmechanism so as to bring about the properly timed operation thereof andenable the plug or needle to assist the sheer mechanism in controllingthe discharge of giessyperticulsriy after the gather of glass has beensevered.

The full nature of the invention will be understood from theaccompanying drewings and the following description and claims: l

in the drawings, Fig. 1 is a central vert cal section through a portionof less tank and its spout and associated glass 'eeding mechanism and amachine for making glassware associated therewith. Figfl is e. planviewof what is shown. in Fi l. Fig. 3 is a vertical section of the shearingor cut-oil mechanism and mold, as shown in i Fig. 1, but. on a. lei- 'erscale.

There is shown in Fig. 1 a part of aglass tank which may he of any desired eon- I with the knife 35 andlongimdineiiy closed after each discharge of shear frame 30. The

The discharge opening 12 is substantleily glass by a needle or plug 15operating vertically through on opening 16 in the top of the specs orboot 11, so as to close and open the. discharge opening. Said needle orplug is pivoted at its upper end to a lever or walking boom 17 andisfulcrumcd between its ends at; 18 to e fixed support 19. Thelcver, orbeam 17 is actuated by 'a connecting rod 20 nivobed at ics upper endthereto.

Thc connecting rod 20 is actuated by an eccentric 21 having a pin 22 towhich the iower end of the connecting rod 20 is pivoted. The eccentric21 is secured on a'sheit 23, seen in Figs. 2 and 9. and said shaftextends through a, frame 524 that is, mounted by upper and lower hearingarms on a verb eel shaft 25 that at its upper end is mounted in iwobearing arms on a frame 26 secured in fixed position; as shown in Figz.l. The shaft 23 has on it a worm Wheel 27 that meshes with a worm 28 onthe shaft 25 so that said vertical shaft 25 drives the horizontsl shaft23 and through intermediate mechanism described. operates the plug orneedle 15. v

The frame. 24, mounted as explained above, is laterally oscillatory andcarries a sheer frame orjber 30 which is fulcrnmed on the shaft 23 by a.pair of divided arms lying on each side of the Worm. Wheel 27,

- so that the sheer frame has a vertical glass opening 31 directly underthe glass discharge opening 12 of the spout ll-and the discharge orgather of glass 13 will pass through said opening. The shear or knife 35lies under the shear frameBO, as seen in Fig. 3, and at one end isprovided with a "that extendiahrough horizontal slots 37 in plates 38secured to the opposite sides of the knife is forwd upbottom of theshear lid-that extends from the sme- 40 rigidly connected near its pivotand extending downwardly therefrom. The other end of the spring 39 issecured to some relative- 1y stationary object, such as the end 124; of

The cam 45is substantial.- ly triangular in shape with a rounded corner 145 auditrotates in the direction of the arrow.

Besidc thc cam 44 there is a smaller cam 46, as seen by dotted lines inFig. 6. In fact, the two cams are begrai, but the small cam. operatesonly in the slot 130 of the shear arm 30. It does not register with theslot 135 in the knife 35, butes the cam is rotated, it engages theuppersurface of the knife and forces it downward, as shown in Figs. 7and 8. The funcpreferably made intion of the large earn 4.5 is to forcethe knife U5 rearwardiy after the shearing operation. In its operationthe periphery of the can] 45 engages the well of the knife at the 'inncrend of the slot 135 and the lug 47 extending upwardly from the knife atthat point,.as shown in Figs. 3 and; 4. As the angular corner of the comduring its operation moves above and away from the lug 47, the knife issuddenly shot forward by the spring 39, fromthe Fig. 3 toihc positionshown in Fig. 6, thus severing the glass 13.

position shown in -The end of the shaft 41 opposite the sprocket wheel42 thereon has secured on it an eccentric consisting of a. oentraliymounted disk 50 with an cccentricaiiy located pin 51 that projectsthrough and operates in a horizontal slot 52 in e stationary frame ormember 53 and is vertically adjustable in fhe end portion 124 of cheieteruliy swinging frame 2/ By this eccentric 50 and the partsdescribed, the free end of the shearing mechanism is vertically movedposition, as shown in the drawings.

The table 71 of the saitl glass blowing ma chine is rotated by a shaft90 which era-insmin: power to a hevele l gear on the underside of aplate 91. aml power is transmitted from that shaft to a shaft 92 and toshaft 25 heretofore described. Plate 91 operates a pitman 191 thatoscillates arm 291 that .intemnittenti ac'tuates the table. There is,therefore, a lixetl relation between the means for rotating the glassmachine table and operating the glass whereby the mold 14- tionforreceiving the glass at'the-proper time, or the glass lSfifiVeIEd anddischarged the'sa me."

stationary frame below the spout on which the rear end ofthe shear armis pivoted to enable the other end of the arm to hav'evertical movement,a shaft extending transversely through said shear arm between its ends,an eccentric securedon said shaft having a pin, a guide secured rigid tothe means on which the shear arm is mounted and having a slot parallelwith the shear arm in which said eccentric pin operates and where-. bvthe shear arm is given vertical movement as the shaft is rotated; aknife mounted in connection withthe shear arm so as to have longitudinalmovement for severing the glass and closing the bottom of the glassopening throng. the shear arm and having a longitudinal slot between itsends, a spring connecting the shear arm and knife for causing theshearing movement of the knife, a cam secured on said shaft for enma amgaging the upper surface of the knife and depressing it after the glasshas been severed, and another cam secured on said shaft and fitting intothe slot inthe knife and causing a return movement of the knife after ithas been depressed.

The combination with the discharge spout of a glasstank having an outletopening in the bottom thereof, of means for controlling the supply ofglass therefrom, including a member movably mounted beneath the spoutwith the opening through it for the flow of glass, a knife mounted onand operating adjacent the underside of said member for severing theglass arranged so that when in severing position the knife will closethe opening to form a cup for temporarily receiving and holding theunoperating said parts so for the flow of glass, a knife mounted on andoperating adjacent the underside of said member for severing the glassarranged so that when in severing position the knifewill close theopening to form a cup for temporarily receiving and holding the.unsevered portion of the glass, a vertically movable plug in the spoutfor controlling the outlet opening, and a common means for operatingsaid parts so that as the glass flows from the tank and before it issevered, said knife holding memberand said plug will be moveddownwardly.

37, The combination with the discharge spout ofa glass tank having anoutlet opening in the bottom thereof, of means for conoperating adjacentthe trolling the supply of glass therefrom, ineluding a member movablymounted beneath the spout with the opening through it for thefiow ofglass, a knife mounted on and underside of said member for severing theglass arranged so that when in severing position the knife will closethe opening to form a cup "for temporarily receiving and holding theunsevered portion of the glass, a vertically movable plug in the spoutfor controlling the outletppening, and a common means for operating saidparts so that as the glass fiows from the tank and before it is severed,said knife holding member and said plug will be moved downwardly, and aknife moved to position preparatory to severmg the glass.

38. The combination with the discharge spout of a glass tank having anoutlet opening in the bottom thereof, of means for controlling thesupply of glass therefrom, ineluding a member movably mounted be neaththe spout with an opening through it for the flow of glass, a knifemounted on and operating adjacent the underside of said -member forsevering the glass arranged So that when in severing position the knifeWlll close the opening to form a cup for temporarilyreceiving andholding the urn severed portion of the glass, means for moving the knifedownward and out of the way of the flow of glass through the opening insaid member after the glass has been severed to prepare for the nextgather of glass, a vertically-movable plug in the spout for controllingthe outlet of glass, and a common means for operating all of saidpartsso that as the gather of glass forms the knife-holding member and plugwill. gradually descend and the knife will bemoved downward from. theknife-holding member and out of the Way of the gather of glass.

In testimony whereof, I have hereunto afiixed my signature.
